1 Claim; (Cl. 68-242) The invention relates to apparatus for drying laundry.

The main object of the invention is to provide an apparatus for expeditiously drying laundry wherein the laundry to be dried is placed in the to an extracting station where the water is removed therefrom, andthereafter the dried clothes may be readily'removed from the extractor body at the extractor station or carried in said body The invention further comprises. a new and body portion of an extractor and moved therein improved form of extractor'apparatus wherein the body of the extractor is adapted to be tilted to discharge its load and is preferably mounted on a wheeled carriage by which it may be readily moved from one station to another.

The invention further consists in an apparatus as hereinafter described and more particularly pointed out in the appended claim.

Fig. 1 is a diagrammatic view of apparatus em bodying the invention;

Fig. 2 is a side elevation view, with parts broken away and parts shown in section, of an extractor apparatus for carrying out the'method embodying the invention;

Fig. 3 is a side view of parts of the apparatus shown in Fig. '1;

Fig. 4 is a detail of a conveyor hook;

Fig. 5 is a detailed side elevation view of a modified form of extractor apparatus;

Fig. 6 is a detailed view, partly in section of certain modifications of the extractor apparatus. Referring to Fig. 1, the numeral I designates washing machines, 8 an extractor body in a loading position, 9 an extractor station, and ID a conveyor. The extractor station 9 may include sets of pairs of extractor bodies and a cover mechanism The extractor bodies may be formed as shown in Fig. 2 wherein the body H is formed as a container having legs l2 secured thereto and provided with wheels l2 and a flexible bag l3 of rubber or other suitable material clamped to the open end of the container by a clamping ring l4 and bolts (not .shown).

The body is also shown as provided with an overflow trough It to whichtubular projections l6 are secured.

Thecover l1, provided with a series of aper-. tures, fits over the top of the body upon the ring I4 and is clamped thereto by a series of latches l8, each pivotally mounted intermediate. its ends.

block 2| which is slidably mounted on a guide rod 22 secured to the cover and is normally urged downwardly by a spring 23. The cover is moved by its suspension from the block 2| through the yoke 24 secured thereto and connected to an arm 25 on a reciprocatory standard 26, said cover preferably being counterweighted by another weighted arm 21. The standard 26 may be raised and lowered in any suitable manner and is shown as hydraulically operated and formed as a piston whose rod and head work in a cylinder 28 formed as a part of a fixed standard, hydraulic fluid being introduced into the chamber at either side through pipe connections 29 and 30 controlled by a suitable three-way valve 3| which connects with a relief pipe 32 or with a pressure supply pipe 33.

With this construction when the standard 26 is raised, the block2l through the sliding connection with the rod 22 is moved upwardly relative to'the cover against the action of the spring 23, and this pulls the links 20 inwardly and hence swings the upper ends of the latches l8 inwardly and thus releases the latches from engagement with the'body of the extractor and thus releases the cover and permits it to be raised and through the turning of the standard 26 to be swung over to the body member at the other side of the standard, so that one cover may be used for a plurality of extractor bodies.

when the bag l3 of the extractor is loaded with wet clothes, and the cover is in closed position. pressure fluid introduced into the container body I I through a pipe 34, from a pipe 34' which is controlled by a suitable three-way valve 35 entractors at the extractor station with a pair of moved from the clothes.
